There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.
Below: Tolkien's Late Period (1950–1973). These are from Tolkien's late conceptual period — his most settled forms of the languages. Prefer these over the earlier ones above when composing new text.
A noun in The Etymologies of the 1930s appearing as {sauro >>} samno “carpenter, wright, builder” derived from primitive ᴹ✶stabnō under the root ᴹ√STAB having to do with (wooden) rooms and buildings (Ety/STAB), where the ancient bn nasalized to mn. For purposes of Neo-Quenya, I would limit this word to one who constructs buildings with wood, as opposed to tautamo as a more general word for a craftsman in wood.
